DS1706TESA/T&R Equivalent & Substitute Parts

Part Overview

The DS1706TESA/T&R is a single-channel power management supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for reset and power-on reset applications in embedded systems. This device operates as a push-pull, totem pole output supervisor with a 3.08V threshold and 130ms minimum reset timeout. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility across voltage monitoring, reset polarity, output configuration, and thermal operating range while accommodating modern RoHS compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS1706TESA/T&R are qualified based on the following critical parameters:

Electrical Compatibility Requirements:

• Single-channel voltage monitoring capability
• 3.08V threshold voltage
• Active Low reset polarity
• Push-Pull or Totem Pole output configuration (or compatible output type)
• Reset timeout between 130ms and 160ms
• Operating temperature range of -40°C to 85°C or wider

Mechanical Compatibility Requirements:

• 8-SOIC package (0.154", 3.90mm Width)
• Surface mount technology
• Moisture Sensitivity Level 1 (Unlimited)

Regulatory & Compliance Considerations:

• RoHS3 compliance preferred for new designs
• REACH Unaffected status
• EAR99 export classification

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications) and manufacturer-recommended alternatives (functionally compatible with minor parameter variations within acceptable engineering tolerances).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): DS1706TESA+T&R is the direct equivalent to DS1706TESA/T&R, offering identical electrical specifications with the advantage of active product status and RoHS3 compliance. This part is recommended as the first choice for new designs and production continuity.

Secondary Substitutes (Functionally Compatible): ADM706TARZ and ADM706TARZ-REEL are manufacturer-recommended alternatives from Analog Devices Inc. Both maintain the 3.08V threshold and active low reset polarity. The reset timeout specification increases to 160ms minimum, which remains within acceptable engineering tolerance for most reset circuit applications. Both parts are active, RoHS3 compliant, and available in high inventory quantities.

Cross-Manufacturer Alternatives: MIC706TMY-TR (Microchip Technology) and SP706TEN-L/TR (MaxLinear, Inc.) provide functional equivalence with 3.08V threshold and active low reset polarity. Reset timeout specifications are 140ms and 140ms respectively, both compatible with the original 130ms minimum requirement. These parts are active and RoHS compliant, offering supply chain diversification. Output configuration details are not specified for these alternatives; verification against specific circuit requirements is necessary before selection.

Compliance Considerations: All recommended substitutes are RoHS compliant, addressing the non-compliance status of the original obsolete part. For applications requiring REACH compliance verification, all listed substitutes maintain REACH Unaffected status. All parts retain EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can DS1706TESA+T&R be used as a direct replacement for DS1706TESA/T&R? A: Yes. DS1706TESA+T&R is electrically and mechanically identical to the original part, with the primary difference being active product status and RoHS3 compliance. No circuit modifications are required.

Q: What is the difference between ADM706TARZ and ADM706TARZ-REEL? A: Both parts are electrically identical with 3.08V threshold and 160ms reset timeout. The primary difference is packaging format: ADM706TARZ is supplied in Tube packaging, while ADM706TARZ-REEL is supplied in Cut Tape and Digi-Reel format. Selection depends on assembly line requirements and inventory management preferences.

Q: Is the 160ms reset timeout of ADM706TARZ compatible with designs using DS1706TESA/T&R? A: The ADM706TARZ reset timeout of 160ms is 30ms longer than the original 130ms specification. This difference is within acceptable engineering tolerance for most reset circuit applications. However, designs with strict reset timing requirements should be evaluated against specific circuit specifications before substitution.

Q: Can MIC706TMY-TR or SP706TEN-L/TR be used interchangeably with DS1706TESA/T&R? A: Both parts maintain the critical 3.08V threshold and active low reset polarity. Reset timeout specifications (140ms) are compatible with the original requirement. However, output configuration details are not fully specified for these alternatives. Circuit-level verification is recommended before production implementation, particularly for applications sensitive to output impedance or drive capability.

Q: Are all substitute parts available in the same 8-SOIC package? A: Yes. All listed substitute parts use the 8-SOIC (0.154", 3.90mm Width) package, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What is the inventory status of these substitute parts? A: DS1706TESA+T&R has 2,280 units in stock. ADM706TARZ has 14,147 units, and ADM706TARZ-REEL has 20,100 units available. MIC706TMY-TR has 3,200 units, and SP706TEN-L/TR has 55,400 units in stock, providing multiple sourcing options for production requirements.

Q: Do all substitute parts meet RoHS compliance requirements? A: Yes. All listed substitute parts are RoHS3 compliant or RoHS compliant, addressing the non-compliance status of the original obsolete DS1706TESA/T&R part.
